  • the device according to the invention has inlets and outlets for the room air to be heated and a liquid to be heated or to be heated, e.g. B. service water. At least the liquid can be stored in a medium container. Furthermore, the liquid can be guided through a medium line, for which purpose a conveying device is provided. A heat exchanger transfers thermal energy to the room air and/or the liquid. The liquid that is guided through the medium line and passes through at least one interaction area of the heat exchanger is heated. Accordingly, the heat exchanger and the medium line are arranged relative to one another. The room air is routed past the heat exchanger in a corresponding manner. As the following configurations show, the device makes it possible, for example, to switch between the media to be heated, i.e.
  • the medium line Prior to an air mode, in which the device is intended to heat room air only, the medium line is drained of liquid by draining or evaporating it due to gravity. This is done by the control unit controlling the conveying device and/or the energy unit in a preparatory step, i.e. before the actual air mode, so that the liquid flows out of the medium line due to gravity and/or is heated in the medium line above its vaporization temperature .
  • the part of the medium line that is located in an effective area of the heat exchanger is relevant in each case. In this way, above all, the liquid that could absorb thermal energy through the heat exchanger is removed.
  • the relevant part of the medium line opens out above the medium container for the outflow caused by gravity and thus using gravity.
  • the control of the delivery device consists, for example, in that no liquid is delivered or that a negative pressure is even generated in the direction of a mouth of the relevant part of the medium line.
  • the alternative or supplementary evaporation occurs, for example, in that the thermal energy generated by the energy unit is increased.
  • the delivery of the liquid is interrupted until the liquid has interacted with the heat exchanger long enough and has absorbed sufficient thermal energy in the process. Vaporizing as opposed to using gravity has the advantage that it can be used for more geometric configurations and arrangements of the components involved. In one embodiment, the liquid runs out first and the remainder is evaporated.
  • the medium container is used to hold liquid and air, and that there is an air cushion in the medium container.
  • the medium container is therefore not completely filled with the liquid during operation, but part of the volume remains, in which an air cushion forms. Therefore, during operation - and in particular during the first start-up - the filling and emptying of the medium container is controlled in such a way that an air cushion is formed.
  • the air cushion also allows the liquid to evaporate.
  • the air in the air cushion is not room air to be heated, which is specifically heated by the device, but is functional or working air.
  • the air cushion results from an additional connection of the medium container to the outside air around the device.
  • One configuration includes that the medium line is used to carry liquid and air, and that the conveying device is used to move liquid and/or air from the medium container to the medium line and from the medium line to the medium container.
  • the liquid branch of the device also contains air, which is conveyed through the medium line.
  • the air from the air cushion can thus be conveyed in a targeted manner through the medium line. This air should not be confused with the room air to be heated.

  • the control unit controls the blower in such a way that room air passes from the air inlet via the heat exchanger to the air outlet.
  • the fan conveys room air in such a way that the heat exchanger transfers thermal energy to the room air and thereby heats it up.

Abstract

L'invention concerne un dispositif pour chauffer de l'air ambiant et un liquide. De l'air ambiant entre dans le dispositif et en sort via une entrée d'air (1) et une sortie d'air (2), et le liquide entre dans le dispositif et en sort via une entrée de liquide (3) et une sortie de liquide (4). L'échangeur de chaleur (6) transfère de l'énergie thermique générée par une unité d'énergie (5) au liquide dans une région d'interaction d'une conduite de milieu (8). Un dispositif de transport (9) déplace le liquide entre un récipient de milieu (7) et une conduite de milieu (8), et une unité de commande (10) commande le dispositif de transport (9) et/ou l'unité d'énergie (5). Si le dispositif doit uniquement chauffer l'air ambiant dans un mode air, l'unité de commande (10) commande le dispositif de transport (9) et/ou l'unité d'énergie (5) dans une étape de préparation, de telle sorte que le liquide s'écoule hors de la conduite de milieu (8) par la force de gravité et/ou le liquide est chauffé jusqu'à une température d'évaporation dans la conduite de milieu (8).
